The pose removes stiffness in the shoulders and corrects any minor deformities in the legs. The ankles become strong and the leg muscles develop evenly. The diaphragm is lifted up and this gives a gentle massage to the heart. The abdominal organs and the back are toned, and the chest is developed by being fully expanded. It is a beneficial pose for horsemen.
